An Advanced CAD-Procedure for the Design and Simulation of Autonomic Systems Applicated to an Integrated Microwave Oscillator

A cad method applied to the development of microwave oscillators

“…The analysis and synthesis of oscillators for microwave and millimeter-wave applications requires the inclusion of a rigorous field theory for the linear environment [21]. In this way an efficient CAD procedure can be used for the design of arbitrarily metallized MIC and MMIC structures.…”

“…It may be useful to obtain minimum calculation time for fast circuit simulation, but it may also be necessary to optimize the quality of the device models The numerical calculation of electromagnetic fields represents a very important basis for the CAD (computer &ded Design) of integrated microwave and millimeter-wave circuits, because such methods can give exact information about the transmission properties of complex structures. The numerical analysis of the resonator structure of the oscillator is of special interest for the design in order to obtain useful equivalent circuits [21]. It is preferable to describe these circuits by analytical expressions to guarantee C A D adaptation [7, 19, 20, 24, 261. Furthermore, the simulation of the oscillator noise behavior is of great importance.…”

“…The measured results shown in this article are obtained with a new measurement system developed in our research group [24].…”
